Thread: What engines to avoid?

I'd stay away from Fords. Chevy's 5.3 is a great engine, very reliable and great gas mileage. The 6.0 is a fantastic engine in regards to power, and while it loves gas, I do hear its a lot better than the dodge 5.9. I have had problems with my 6.0, getting this multiple misfire code from hell all the time, the truck runs fine though, i hear its pretty common and hard to get rid of, I've replaced a lot of things trying to get the damn light to go away, no such luck but it runs decent and plows and tows like a boss so i guess i can't complain.

btw, I'm right down the northway from ya Jay. If yer plowin up there, I think you'll definitely want more power than the 5.3

In reguards to your multiple misfire have you tryed a crank re-learn ?

Please enlighten me. I've never had a transmission problem with any of my GM's, and I've never heard of any widespread transmission issues with GM trucks. They start to have problems around 200,000-250,000 miles. About the same time as most Ford's.Posted via Mobile Device

I posted above that i put in 2 transmissions in a chevy. The first at 130k and the second at 215k. One of my subs has put in 2 in his chevy within 230k miles.

There not as bad as dodges but I wouldnt say its not a problem.

To me theres not a big difference in either truck. I own 3 chevys and 2 fords. Almost bought another chevy but passed.

Yeah, I saw that. I know you had problems with your Chev, but again two guys having to replace transmissions in 1500's that I assume have plowed (since you have a "sub" I assume you're pushing snow with the truck) is NOT a widespread problem. For every guy on here that has had problems with their GM truck I can find 3 Ford owners who've had it worse. While I consider myself a GM guy, I too own Ford trucks as well as GM and have had Ford's that never gave us a problem, and ones that were total POS's. I've had problems with GM trucks too, but never major ones, just little annoyances.Posted via Mobile Device

Couple times, no such luck. I've replaced all the o2 sensors also, but I think I've narrowed it down to a bad computer, or one of the o2 sensors i've replaced has already gone bad...who knows. Been living with it as pouring money in hasn't really been fixing anything. Ha the only thing I haven't replaced right about now is the frame and the body!

F150s... the 04 or 05+ got the 3valve heads and thats the ones that have the sparkplugs snap when trying to remove them unless someone changed them or added antiseize early on...

F250s+/superduty trucks with the 5.4L got 3valve heads in 05 i think, don't quote me on that, were basically told a high mileage 2007 F250 needed a whole engine because shop couldnt get the last 3 plugs out, or pieces of them... Had a neighbor finish the job for $400 and truck is perfect now.

On the GM tranny thing I don't know a chevy in the late 90's to mid 2000's who hasn't had tranny issues. Its alway at the 130k mark it seems. Also rear ends are an issue too, same with dodge. Dodge motors are darn near bullet proof except for intake manifold leaks. I just did mine at 200k. Also never had a tranny issue and I have 60k of trailer hauling milage. I will say my 5.2 has some gonads. But 10mpg pulling a trailer and 14 hyway.
